Hi Guys
I have transplanted a vy motor and auto trans into a ford transit and everything is good except the auto electrician didn't connect the auto transmission and its stuck in limp mode which apparently is 3rd gear. Any advice how I can power up trans.
Loom is all connect to ecu.
Thanks Norm

What engine is it? Ecotec? L67? LS1?
What loom did you use?

Hi
I am sure it is ecotech. I bought it from a running car with ecu and existing loom all complete.. not sure if L67 or ls1 how can I tell. Are there different looms.
